Before and After Pictures from Vienna
Vienna VA Home Remodel with Insulation

Vienna VA Home Remodel with Insulation

Before After
Vienna VA Home Remodel with Insulation Vienna VA Home Remodel with Insulation

This Vienna VA home was being remodeled and had its interior frame stripped down to allow for installation of more modern insulation products.  Our team started working in the attic before addressing the inside of the walls in the rooms below.  Old insulation was removed and the attic was air sealed with Zyp Foam in order to control unwanted air flow in and out of the space.  A new attic floor decking was constructed by our team along with damning/walls to hold in the Tru Soft Cellulose Insulation that would later be blown in.  A zippered Attic Tent door cover was installed to properly seal up the attic door and control air loss from the rooms below.  The final result for the attic was a thick layer of insulation and a more energy efficient top floor of the home.  The floor/decking would allow for storage space and the ability to walk around the attic.

An unprotected HVAC duct system can leave you with an uncomfortable home and higher energy bills than you should have.  Conditioned air, heated or cooled by the HVAC system is intended to pass through HVAC ducts to get to the different rooms in a home.  If the temperature in an attic is 125 degrees in the summer, the cold air trying to move through the HVAC duct is in a hostile environment.  Same idea in the winter.  If it is 25 degrees in an attic, the 74 degree heated air trying to pass through the HVAC ducts is fighting to stay warm.  Insulating ducts with spray foam helps protect that air and eliminates air leakage at joints and turns in the duct system.  The insulation wrap that had been used to try and protect this duct systems was eaten through by rodents and had multiple holes and tears.

Expert Spray Foam Insulation Company

At one point pink fiberglass insulation was the best option for home insulation. However, today spray foam insulation is the much better option. Spray foam insulation has several benefits and beats the traditional fiber-glass product in every way. Spray foam insulation is the top choice for homeowners, contractors, and building scientists (the experts who study home energy performance) for several reasons. Here are the top reasons spray foam insulation should be your number 1 choice:

Advantages of Spray Foam Insulation:

  • Provides both insulation and air sealing
  • Fills gaps and cracks
  • High R-value
  • Speedy installation
  • Spray foam won't shift, settle, or fall out of place

Help Your Home with Attic Insulation

Upgrading your home’s attic insulation is a very effective & popular energy-saving method because there is usually a lot of room for improvement. Most homeowners believe their attic has enough insulation but once we explain how much insulation is actually needed to make your home efficient people understand that they don’t have anywhere near enough. It is common knowledge that hot air rises which is why a properly insulation attic is one of the most important things you can do for your home. By adding attic insulation to your home you are guaranteeing to save money and also have a more comfortable home. Not having a properly insulated attic is equivalent to constantly leaving one of your windows open. Don’t wait any longer to learn more about the attic insulation methods we have available in your area!.

Crawl Space Insulation Experts

Do you need crawl space insulation installed or replaced? If so, you're in the right place! A damp crawl space with falling or sagging insulation usually means the space has a moisture problem. If that is the case our team of experts can provide a vapor barrier to keep moisture out of your crawl space. We can then replace your existing insulation with a better option such as rigid foam or spray foam insulation. If your crawl space is completely missing insulation then your home is most likely cold and drafty. This is because the environment in your crawl space will transfer to other parts of your home, which is why proper crawl space insulation is essential to keeping your home comfortable and your energy bills low. To learn more about crawl space insulation cost, call, or click today!
